Sound not working after Installing Windows 7

Today i installed windows 7 in my friends PC .. He was using Win XP before .. Everything went smoothly but sound isnt working .. I checked in device manager under "sound, video and game controllers" and it says "High Definition Audio Device." .. I double clicked it n it said driver is working properly.. Double checked the speakers..they r also fine n working .. so whats the prob here?? His sound was working fine in XP ..

Could it happen for a faulty DVD?? Should I reinstall windows ? or r there any other solutions?

Right click on that "High Definition Audio Device" and choose uninstall, reboot the pc and check whether its working, if not then you need to have the driver for that sound card you have. Google the model number of that sound card, you may find the driver online.

Actually I saw that in a forum .. Someone fixed it by doing that .. The PC isnt mine so I didnt check .. I told him to do it.. My frnd said everything is enabled in The Audio section .. So its must b the audio driver

If that is off within the BIOS, your device manager won't even recognize there's an available sound DAC in your system. If it's enabled, Windows 7's own buitlin drivers should be enough for atleast listening to a song/video. Make you install the correct drivers, download from Realtek's own website- they have the latest ones there.
